PIPE AND ROD GRIPPING DEVICE.

b all whom it may concern:

Be it known that I, J OI-IN KEMMLER, a citizen of the United States ofAmerica, residing at Trestle P. 0., in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inPipe and Rod Gripping Devices, of which the following-is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a pipe and rod gripping device and theinvention has for its object to provide a simple and durable device forobtaining a positive grip upon a pipe or rod, whereby said pipe or rodcan be easily moved, either manually or by attaching a suitable pullingmechanism to the device.

A further object of the invention is to provide a pipe and rod grippingdevice with removable gripping blocks, whereby various sizes of blockscan be used for gripping pipes and rods of various diameters.

With the above and other objects in view which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be hereinafterdescribed and then claimed.

Referring to the drawings :Figure 1 is a plan of a pipe and rod grippingdevice constructed in accordance with my invention, Fig. 2 is a sideelevation of the same, Fig. 3 is a longitudinal sectional view of thedevice, Fig. 4: is a bottom plan of one of the gripping members.

In the drawings, 1 and 2 designate two parallel oblong links having theends thereof connected by bolts 3 and 4, and nuts 5, the link 2 havingone end thereof provided with an open end slot 6, whereby said link canbe swung into and out of engagement with the bolt 4:, the object ofwhich will presently appear.

Pivotally mounted upon the bolts 3 and 4 are gripping members 7 havingthe pivoted ends thereof provided with handles 8 of a suflicient lengthto permit of considerable leverage being obtained when using the device.The members 7 confront one another and have their inner ends cut away,as at 9, for pipe clearance and toothed or serrated Specification ofLetters Patent.

as at 10, for positively gripping a pipe or rod 11.

With the link 2 loose at one end, it is not necessary to place thedevice down over the end of the pipe or rod, as the link can be opened,and the handles 8 brought downwardly together, whereby the device can beslipped upon a pipe or rod, the link closed, and then the handles 8brought into longitudinal alinement whereby the teeth or serrations ofthe members 7 will bite into the pipe or rod and firmly grip the same.

It will be observed from the foregoing description that I have devised anovel pipe grip and lift, and that in many instances it will beunnecessary 'to use derricks or chain blocks to assist in elevatingpipes that could not be otherwise easily moved without my grip.

lVhile in the drawings there has been illustrated the preferredembodiments of the invention, I would have it understood that the detailconstruction thereof can be varied or changed as to shape, proportionand manner of assemblage without departing from the spirit of theinvention.

Having now described my invention what I claim as new, is

A pipe clamp adapted for sidewise mounting on a pipe comprising astationary and a pivoted link, means for connecting said links togetherin spaced relation, a pair of pipe gripping members pivotally mounted onsaid means and between said links and having the opposing faces thereofbeveled, each of said beveled faces formed throughout with asemi-cylindrical pipe clearance and with the upper portion of the walltoothed, and an elongated hand grip eXtend ing from the outer end ofeach of said members for manually operating it, and said pivoted linkprovided with a recess at one end for engaging the connect-ing meanswhereby the same can be swung back to allow sidewise application of theclamp upon the pipe.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JOHN KEMMLER.
